Now that the Motu Proprio Summorum Pontificum has been made public, the disinformation campaign will start. One of the most subtle poisons being disseminated is that the priest faces away from the congregation. How often does one read this in the newspapers or from other sources? It is being spread and constantly repeated as if to brainwash the people.
No. That is an illogical perspective.
The logical perspective is this: he does so, so that he would face, with that same congregation, the Lord on the cross and lead them to prayer.
Would you rather let the priest turn his back against the Lord so that he could turn to you instead? I hope we'd rather let the priest face the Lord and give the Lord reverence due Him.
